Description:
Ornendil was the elder son of Eldacar, and so at least 1/4 Northman. We know almost nothing of him, save that he was captured during the fall of Osgiliath during the Kin-Strife. He survived the city's fall only to be executed by Castamir.

Ornendil's name seems to be a combination of "orn" ("tree"), and "-ndil", a component meaning "friend".

The limit on his date of birth comes from The Peoples of Middle-earth, where his younger brother, Aldamir's, birthday is given as 1330, T.A.
